Total 12v electrical failure- 2020 View 24J

[Dmarcian]

No 12 volt system at all. Happened when I tried to start the generator. I heard a pop and then everything shut down. Xantrex controller 601 fault - battery disconnect. All fuses seem ok but I don’t know where the main fuse coming off the batteries (40 or 60 amp). Can anyone point me in the right direction? Fortunately I am on my way to Forest City to have the service center fix a bunch of things. 3 day drive and I would really appreciate 12 volt power. Inverter works by the way.

If the inverter still works, that means it is getting 12V through its own breaker. That means your supposition that it is a main DC breaker that has tripped is probably correct. Can't help you with the location but you also need to find the cause of why it tripped.

It does seem related to the generator starting circuit. Usually that is protected by a separate 100A breaker from the circuit that powers the converter, so it is puzzling why the converter circuit shut down.

Basically you need to follow the circuits with a voltmeter and see where it is open.

There are lots of diagrams and drawings online to look for this sort of things but you'venot given any idea of what RV year, and make you are asking about, so there is no way to say where parts might be located or even if you have that part! Very few will know what a 20VJ is without a lot of looking!

Meantime it might be worth noting that you DO have 12 volt power if the engine starts and the inverter works as they both need 12 volts??

This is the color code for battery cables if they are still on your Rv as they tend to drop off as it gets older.

2020 View J. It was in the title line. Chassis electric fine. Trying to find the Xantrex fuse. I have power to the inverter but no 12 volt power to lights, fridge etc. batteries fully charged. Thanks
